Filed: 1985-10-31
Abstract: PURPOSE:To obtain a gyrocompass with which a high-precision azimuth is obtained by varying a liquid tank by a fine angle periodically and forcibly irrelevantly to the azimuth of a rolling ball and thus eliminating the static friction of mercury. CONSTITUTION:The deviation between the azimuth of the rolling ball and the azimuth of the liquid tank which is generated between follow-up electrodes 7A and 7B and a beltlike electrode 8 is inputted to a deviation detection part 9 and made into a deviation voltage, which is amplified 92 and outputted to a servomotor 10. This circuit 12 is provided with switches S1-S3 which switches connections among parallel DC electrodes 13 and 14 with the mutually opposite polarities, a detection part 91, and an amplification part 92, and a switch switching control part 15 which performs switching control over the switches at constant timing. Namely, the liquid tank 2 is rotated by the fine angle in the alternate opposite directions at a period at which there is no influence exerted upon the azimuth of the rolling ball, thereby varying the azimuth of the liquid tank forcibly. Thus, the liquid crystal azimuth is rotated by the constant angle for a constant time periodically to eliminate the static friction of mercury equivalently.

Title: Correcting device for welding strain of panel for steel structure
Inventor: TAKAHATA SEIJI
IPC: G01B11/03
Filed: 1992-08-20
Abstract: PURPOSE:To safely and easily positioning by monitoring a position having a welding strain to be corrected by pressing using a laser beam and a telecamera. CONSTITUTION:Since a strain is generated when a vertical stiffener 11 is welded to a steel plate 10 of a box girder for web, the strain is corrected by an upper metallic die 16 and lower metallic die 17. The upper metallic die 16 is remote controlled to be positioned seeing an image in the telecamera 19 so as to the laser beam S from a laser beam oscillator 18 is projected toward the center part of the vertical stiffener 11 in its width direction. Since the lower metallic die 17 is always positioned at the center part of the upper metallic die 16, the lower metallic die 17 is elevated when the laser beam S is projected on the center of the vertical stiffener 11 in its width direction. Thus, the steel plate 10 is horizontally corrected and the welding strain is eliminated.

Filed: 1991-09-25
Abstract: PURPOSE:To treat at a high temperature after Al of a wiring electrode is formed by forming an upper electrode of a capacitor made of a ferroelectric material of a conductive film containing Pt as a main ingredient and a laminated structure of Ti, TiN, etc. CONSTITUTION:An upper Pt electrode 110 is formed in contact with a ferroelectric film 109 by a sputtering method of Pt. An upper Ti electrode 111 is formed of Ti, TiH by a sputtering method. After an interlayer insulating film between a wiring electrode 112 and a ferroelectric capacitor is formed, an Al wiring electrode 113 is formed by a sputtering method. Since the electrode 113 is brought into contact with Ti, TiN, a heat treatment of about 500 deg.C can be performed even after the Al electrode is formed to be sufficiently durable against formation of a passivation. The Pt is brought into direct contact with the ferroelectric film to improve characteristics of the capacitor. Such a structure is formed thereby to selectively set the electrode 110 without considering reactivity with the Al of the wiring electrode.
